Background
The Common Access Control Component was developed to provide a consistent interface for Windchill ProjectLink and Windchill PDMLink users to view and manipulate access control permissions on individual Windchill objects. The feature is available in the out of the box Security Clerk through the Edit Access Control action and also in the Create Document and Create Part wizards.
To learn more about the Edit Access Control action and window, see Editing Access Control for an Existing Object.
This feature for individual object instances is implemented using ad hoc ACLS. The access component for a folder also has the additional capability of defining permissions and propagating them throughout the folder contents.
Preferences are supported to permit sites to tailor the visibility and updatability of individual access control permissions to meet their specific access control requirements.
